Automation Testing Services:

We offer Test Automation services to various clients.

Software tests have to be repeated often during development cycles to ensure quality. Every time source code is modified software tests should be repeated. For each release of the software, it may be tested on all supported operating systems and hardware configurations. Manually repeating these tests is costly and time consuming. Once created, automated tests can be run over and over again at no additional cost and they are much faster than manual tests. Automated software testing can reduce the time to run repetitive tests from days to hours. A time savings that translates directly into cost savings.

We offer Automation Testing services by using various tools like Selenium, Appium, Cucumber, Siltest, Egg plant..etc.

  • Type of Automation tests we do are
  • Code Analysis
  • Unit Tests
  • Integration Tests
  • Automated Acceptance Tests
  • Regression Tests
  • Performance Tests
  • Smoke Tests

Manual Testing:

Manual Testing is a type of software testing in which test cases are executed manually by a tester without using any automated tools. The purpose of Manual Testing is to identify the bugs, issues, and defects in the software application. Any new application must be manually tested before its testing can be automated. Manual Software Testing requires more effort but is necessary to check automation feasibility.

  • How we perform Manual Testing
  • Read and understand the software project documentation/guides. Also, study the Application Under Test (AUT) if available.
  • Draft Test cases that cover all the requirements mentioned in the documentation.
  • Review and baseline the test cases with Team Lead, Client (as applicable)
  • Execute the test cases on the AUT
  • Report bugs.
  • Once bugs are fixed, again execute the failing test cases to verify they pass.

Types of Manual Testing

Performance Testing:

We offer Performance Testing Services. Performance testing is a testing measure that evaluates the speed, responsiveness and stability of a computer, network, software program or device under a workload.

Without some form of performance testing in place, system performance will likely be affected with slow response times, experiences that are inconsistent between users and the operating system, creating an overall poor user experience. Determining if the developed system meets speed, responsiveness and stability requirements while under workloads will help ensure a more positive user experience.

Why use our performance testing services?

An organization can use performance testing as a diagnostic aid to locate computing or communications bottlenecks within a system. Bottlenecks are a single point or component within a system's overall function that holds back overall performance. For example, even the fastest computer will function poorly on the web if the bandwidth is less than 1 megabit per second. Slow data transfer rates might be inherent in hardware but could also result from software-related problems -- such as too many applications running at the same time or a corrupted file in a web browser.

Functional Testing:

FUNCTIONAL TESTING is a type of software testing that validates the software system against the functional requirements/specifications. The purpose of Functional tests is to test each business function of the software application, by providing appropriate input test data and verifying the output against the Functional requirements. This testing; checks User Interface, APIs, Database, Security, Client/Server communication and other functionality of the Application Under Test. The testing can be done either manually or using automation.

  • Examples of Functional testing are
  • Unit Testing
  • Smoke Testing
  • Sanity Testing
  • Integration Testing
  • White box testing
  • Black Box testing
  • User Acceptance testing
  • Regression Testing
  • Functional Testing Tools
  • Selenium - Popular Open Source Functional Testing Tool
  • QTP - Very user-friendly Functional Test tool by HP
  • JUnit- Used mainly for Java applications and this can be used in Unit and System Testing
  • soapUI - This is an open source functional testing tool used for Web service testing. It supports multiple protocols such as HTTP, SOAP, and JDBC.

Non-Functional Testing:

NON-FUNCTIONAL TESTING is defined as a type of Software testing to check non-functional aspects (performance, usability, reliability, etc) of a software application. It is designed to test the readiness of a system as per non-functional parameters which are never addressed by functional testing.

  • Objectives of Non-functional testing
  • Non-functional testing should increase usability, efficiency, maintainability, and portability of the product.
  • Helps to reduce production risk and cost associated with non-functional aspects of the product.
  • Optimize the way product is installed, setup, executes, managed and monitored.
  • Collect and produce measurements, and metrics for internal research and development.
  • Improve and enhance knowledge of the product behavior and technologies in use.
  • Non-Functional Test Tools
  • JMeter used for compatibility testing, measuring and analysing performance of programs.
  • Loadster offers quality results in volume testing parameters of the software system.
  • Loadrunner is one of the most widely used performance testing tools.
  • Loadstorm is available to test various program components.

Mobile Apps Testing:

Mobile application testing is a process by which application software developed for handheld mobile devices is tested for its functionality, usability and consistency. Mobile app testing can be an automated or manual type of testing.

  • Types of mobile application testing
  • Functional testing ensures that the application is working as per the requirements. The tests conducted for this is driven by the user interface and call flow.
  • Laboratory testing, This test is performed to find out any glitches when a mobile application uses voice and/or data connection to perform some functions.
  • Performance testing is undertaken to check the performance and behavior of the application under certain conditions such as low battery, bad network coverage, low available memory, simultaneous access to the application's server by several users and other conditions. Performance of an application can be affected from two sides: the application's server side and client's side. Performance testing is carried out to check both.
  • Memory leakage testing: Memory leakage happens when a computer program or application is unable to manage the memory it is allocated resulting in poor performance of the application and the overall slowdown of the system. As mobile devices have significant constraints of available memory, memory leakage testing is crucial for the proper functioning of an application
  • Interrupt testing: An application while functioning may face several interruptions like incoming calls or network coverage outage and recovery. The different types of interruptions are:
    • Incoming and outgoing SMS and MMS
    • Incoming and outgoing calls
    • Incoming notifications
    • Battery removal
    • Cable insertion and removal for data transfer
    • Network outage and recovery
    • Media player on/off
    • Device power cycle
    An application should be able to handle these interruptions by going into a suspended state and resuming afterwards.
  • Usability testing is carried out to verify if the application is achieving its goals and getting a favourable response from users. This is important as the usability of an application is its key to commercial success (it is nothing but user friendliness). Another important part of usability testing is to make sure that the user experience is uniform across all devices. This section of testing hopes to address the key challenges of the variety of mobile devices and the diversity in mobile platforms/OS, which is also called device fragmentation. One key portion of this type of usability testing is to be sure that there are no major errors in the functionality, placement, or sizing of the user interface on different devices.
  • Installation testing: Certain mobile applications come pre-installed on the device whereas others have to be installed by the store. Installation testing verifies that the installation process goes smoothly without the user having to face any difficulty. This testing process covers installation, updating and uninstalling of an application
  • Certification testing: To get a certificate of compliance, each mobile device needs to be tested against the guidelines set by different mobile platforms.
  • Security testing: Checks vulnerabilities to hacking, authentication and authorization policies, data security, session management and other security standards.
  • Location testing: Connectivity changes with network and location, but you can't mimic those fluctuating conditions in a lab. Only in Country, non-automated testers can perform comprehensive usability and functionality testing.
  • Outdated software testing: Not everyone regularly updates their operating system. Some Android users might not even have access to the newest version. Professional testers can test outdated software.
  • Load testing: When many users all attempt to download, load, and use an app or game simultaneously, slow load times or crashes can occur causing many customers to abandon your app, game, or website. In-country human testing done manually is the most effective way to test load.
  • Black-box testing: Where the application is tested without looking at the applications code and logic. The tester has specific test data to input and the corresponding output that the application should produce, and inputs the test data looking for the program to output data consistent with what the tester was expecting. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.
  • Crowdsourced testing: In recent years, crowdsourced testing has become popular as companies can test mobile applications faster and cheaper using a global community of testers. Due to growing diversity of devices and operating systems as well as localization needs, it is difficult to comprehensively test mobile applications with small in-house testing teams. A global community of testers provides easy access to different devices and platforms. A globally distributed team can also test it in multiple locations and under different network conditions. Finally, localization issues can be tested by hiring testers in required geographies. Since real users using real devices test the application, this is more likely to find issues faced by users under real world conditions.

Telecom Testing:

Telecom Testing is defined as the testing of Telecommunication software. Since the shift of the telecom sector to digital and computer networks, telecommunication industry uses software indispensable. Telecom sector depends on the various types of software components to deliver many services like routing and switching, VoIP broadband access, etc. Hence, telecom software testing is inevitable.
